6 Shi (C This invention relates to a combination bafile plate and settle-blow mechanism adaptable for glassware forming machines.

, One object of the invention is to provide a combination baffle plate and settle-blow mechanism so designed as to minimize the number of operations during the charging a parison therein.

adjacent portions of the parison molds as taken on the line 3-3 of Fig. 2 with a valve mechanism at the left side of the figure being taken on the line 3 and 3a of Fig. 2;

Fig. 4 is a vertical sectional view on the line H of Fig. 2;

Fig. 5 is a horizontal sectional view on the line 5-1-5 of Fig. 3; a

Fig. 6 is a sectional view similar to a portion of Fig. 3 showing the parts in a different position duringthe cycle of operations; and

Fig. 6A is an enlargement of a portion of Fig. 6 to show details of clearance spaces.

On the accompanying drawings I have sed he refer.- ence numeral 10 to indicate a supporting arm for my combination bafile plate and settle blow mechanism. A supporting bracket 12 is adjustably clamped by a clamp 13 and clamp bolts 15 as shown in Fig. 2 to the sup- 7, porting armf10 so that it may be adjusted in elevation to '20 of a parison mold and during the complete forming of Another object is to provide a mechanism of the character described which involves only seven steps in the forming of a parison as follows:

Still another object is to provide baffle plate actuating mechanism for spacing a baflle plate from a parison mold as a bafile guide ring is engaged with the mold, and at the same time introduce settle-blow air under pressure that may readily flow under the baflie plate and into the mold cavity on top of the charge of glass, thus insuring" proper formation of the finish on the parison around the finish pin.

A further object is to provide means to engage and seat the bafile on the mold and simultaneously shut off the flow of settle-blow air preparatory to the mold receiving counter-blow air after the plunger is withdrawn from the expands within the mold cavity as a result of tion of counter-blow air thereinto.

Still a further object is to provide means for thendisengaging the baffie plate guide ring and the baffle plate f rom the mold, thus completing the parison forming operation and preparing the baffle plate and settleblow mechanism for coaction with another parison mold brought into position beneath the bafile plate mechanism for the forming of the next parison therein.

With these and other objects in view, my invention consists in the constructiomarrangement and combination of the various parts of my baflle plate and settle-blow mechanism, whereby the objects above contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in detail on the accompanying drawings, wherein:

Fig. l is a vertical sectional view through a parison mold with finish ring, finish pin and funnel engaged therewith, a gob of glass having just been deposited therein during a cycle of parison forming operations, a double gob type of parison mold being illustrated;

Fig. 2 is a plan view of a combination baflle plate and settle-blow mechanism comprising my present invention;

A bafile plate guide ring' 18 issupportedin tie: pending position from the baffie plate guide ring he d; 20 and a baflle plate 22 is vertically recipro iibl'eflm e. bore 33 of the ring 18. The head 19'of the' neck; 1 7 is received in an undercut slot 21 of the batfiepIate-guidea ring head '20 for supporting the latter from the cap 116' and thence by the cylinder block 14 and the supporting;

bracket 12.

A parison mold of split construction is shown ,at 24 and is adapted for coaction with the guide ring 18 and the bathe plate-22 as will hereinafter appear. Each-half of the parison mold is'supported by a parison mold holder shows the'parison mold holder 26 supported by par son mold holder arms 28, and a funnel 30 is-fe n'gaged with/Y the 'parison mold through which the gob of-gla'ssdl' is introduced into the mold. A funnel supporting arm" is shown at 32. t 1 v.

In 3 a baffle plate piston 34 is showni from which extends a bafiie plate piston rod 36. vThis ;1' orl-,is slidable through a bushing 38 carried by the bafile plate cylinder cap 16 and extends through rocker washers 40 which permit proper seating of the guide ring 18 and the battle plate 22 on the mold 24.

At.42 I illustrate a cam in the form of a truncated;

At this time, the machine timer is introducing air through the air connections 52 for holding the two pistons 34 in their raised position and the bafiie plates 22 spaced from theupper ends of the parison molds. The cams 42 are in their raised positions also for opening the settle-blow air valves 58. Accordingly, air constantly supplied to the air connections 64, passes through the passageways 48 past the valve seats 60 and through the passageways 68 and 70 and the annular passageways 72 to the vent grooves 74 as indicated by the arrows for settling the gobs 31 down against the finish pins 27 and properly into the finish rings 29 for compacting the gobs of glass 31 against the surfaces thereof and thereby forming perfect finishes (step 5).

Step 6 is illustrated in Fig. 6, air having been cut off to the connection 52 and air introduced into the connection 50 for moving the bafiie plate 22 downwardly from r the position of Fig. 3 to the position of Fig. 6 which seats the bafile plate on the parison mold so that the uncovered by the stem 62 as the settle-blow air valve is seated by its spring 59 as shown in Fig. 6.
